United States Food Law Update: Moving Toward A More Balanced Food Regulatory Regime, A. Bryan Endres, Nicholas R. Johnson

Journal of Food Law & Policy

For decades, the federal government has played a significant role in promoting healthy eating. In the early 1900s, the United States Department of Agriculture (USDA) promoted a foundational diet of milk, proteins, fruits and vegetables, and grains. Most Americans are at least somewhat familiar, although perhaps confused, with the more nuanced healthy eating recommendations contained in the food pyramid - first employed in 1992. And virtually every American has experienced the federally supported school lunch program. In the first half of 2011, these two iconic programs underwent significant change as part of a stepped-up effort to improve the health of …

Thermal Tolerance Of Age-0 Gulf Of Mexico Striped Bass (Morone Saxatilis): Ontogenetic And Genetic Effects, Corey Robert Anderson

Master's Theses

Striped bass, Morone saxatilis, were historically abundant in the Gulf of Mexico region but were largely extirpated from most Gulf rivers by the early 1960s. Since 1967 hatchery stocking has supported populations in Mississippi rivers and to date there is no evidence of natural reproduction. Intolerance of striped bass to high water temperature is a potential factor negatively impacting Gulf striped bass survival and reproductive fitness, and may be a limiting factor to reintroduction of the species in Mississippi. This work contributed to restoration efforts by establishing molecular tools necessary for genetic monitoring of striped bass restoration, and evaluating …

Mapping Extension's Networks: Using Social Network Analysis To Explore Extension's Outreach, Tom Bartholomay, Scott Chazdon, Mary S. Marczak, Kathrin C. Walker

Journal of Extension

The University of Minnesota Extension conducted a social network analysis (SNA) to examine its outreach to organizations external to the University of Minnesota. The study found that its outreach network was both broad in its reach and strong in its connections. The study found that SNA offers a unique method for describing and measuring Extension outreach and that SNA can be effectively used to examine internal patterns around outreach while informing strategies toward improved alignment and greater leveraging of institutional knowledge. The findings indicate that SNA has great potential for improving reporting, developing internal collaboration, and conducting system-wide impact evaluations.

According to research, there is some skepticism in some areas as to the effectiveness of their subliminal messages. However, it is clear that there is some recognizable effect; statistics show an increase in obesity and self-image and self-esteem problems spurred on by subliminal messaging in television and film aimed at the young. The selected literature included well-known books on subliminal messages and other materials covering 50 years of research. The literature also …

A Critical Analysis Of Direct To Consumer Advertising Of Prescription Medications Using Language Expectancy Theory, Lisa Marie Emig

Communication & Leadership Dissertations and Theses

This thesis explores the relationship of Direct to Consumer Advertising (DTCA) and Language Expectancy Theory (LET) by conducting a critical analysis of three medications used to treat depression. Society and the medical profession have created a dichotomy between the well and pathological state. The study reviews if DTCA uses language and visual cues to influence the use of medications, to downplay potential side effects, to portray life as better when taking a medication and to remove personal responsibility for health. There are common elements used in DTCA of antidepressants. The review of the common elements shows the use of specific …

The Cytoplasmic Tail Of Mhc Class I Molecules Plays A Critical Role In Dendritic Cell-Induced T Cell Immunity, Tania G. Rodriguez-Cruz

Dissertations and Theses (Open Access)

The presentation of MHC class I (MHC-I)/peptide complexes by dendritic cells (DCs) is critical for the maintenance of central tolerance to self and for the regulation of cytotoxic T lymphocytes (CTL)-mediated adaptive immune responses against pathogens and cancer cells. Interestingly, several findings have suggested that the cytoplasmic tail of MHC class I plays a functional role in the regulation of CTL immune responses. For example, our previous studies demonstrated that exon 7-deleted MHC-I molecules not only showed extended DC cell surface half-lives but also induced significantly increased CTL responses to viral challange invivo. Although exon 7-deleted variant of MHC-I does …

In this study, key organizations and researchers working in the field of appropriate technology (AT) were interviewed to identify barriers to OSAT. The data was analyzed via pattern coding and content analysis. Results reveal that among the most pressing problems for those working in the field of AT were the need for better communication and collaboration between the agencies and communities to share …

Life History Tradeoffs And Phenotypic Plasticity: The Tale Of A Flight Polyphenic Field Cricket, Chandreyee Mitra

School of Biological Sciences: Dissertations, Theses, and Student Research

Most organisms are resource limited. Such limitations can result in tradeoffs between life history traits -- any traits that affect survival or reproduction. Flight polyphenic field crickets are thought to be a classic example of such a life history tradeoff, in which individuals tradeoff investment in flight capability and investment in reproduction. This polyphenism results from the interaction of two morphological traits: wing morphology (short or long) and flight muscle morphology (functional pink or non-functional white), and is affected by both genes and the environment. I examined life history traits of a flight polyphenic field cricket, Gryllus lineaticeps. First, …

Effect Of Diet Quantity And Quality On Female Sampling Behavior And Mating Preferences In A Field Cricket, Heidi L. Bulfer

School of Biological Sciences: Dissertations, Theses, and Student Research

Understanding the adaptive significance of variation in female mating behaviour is important because variation may often be favored by selection instead of a change in mean mating behaviour, particularly in variable environments. Females are known to adjust their mating behaviour to a variety of intrinsic and extrinsic factors including nutrition. There are multiple reasons why female behaviours might vary with nutrition; we tested two of these hypotheses: the search cost hypothesis and the direct benefits hypothesis. These hypotheses are not mutually exclusive, but they make contrasting predictions under some conditions. Low nutrition females may have less available energy to support …

The Relationship Between Physical Activity And Cognitive Symptoms Of Depression, Katy Manganella

Psychology and Counseling Theses

Existing research on exercise habits typically focuses on the physical health benefits. However, this research tends to neglect the potential psychological benefits of exercise. The present research adopts a different perspective by investigating the relationship between exercise and different symptom types of depression. By establishing the amount of physical activity participants consider to constitute exercising on a regular basis, participants were separated into self-reported high and low-exercise groups and completed the Zung-Self Rating Depression Scale. By employing a factor analysis of the Zung SDS, the results were analyzed assessing each symptom type of depression: Cognitive, affective, and somatic. Results suggest …

Foliar Symptoms Of Acute Ozone Injury And Exposure Response Characteristics Of Select Native Perennials, Susan Denise Frey

Graduate Theses and Dissertations

Twenty seven perennial species native to the Eastern Temperate Forests Level I Ecoregion were exposed to an acute ozone (O3) treatment consisting of a target peak O3 concentration of 2.0 ppm for 30 minutes in a closed chamber environment, during the summer of 2010. Plants were evaluated for visible foliar injury symptoms and symptoms were described and photographically documented. Ten of the 27 species developed visible foliar injury in which interspecific and intraspecific response to O3 was observed. A severity index was used to compare response to acute ozone exposure for the ten species displaying visible foliar injury. Species showing …

Systematics Of Protosteloid Amoebae, Lora Lindley Shadwick

Graduate Theses and Dissertations

Because of their simple fruiting bodies consisting of one to a few spores atop a finely tapering stalk, protosteloid amoebae, previously called protostelids, were thought of as primitive members of the Eumycetozoa sensu Olive 1975. The studies presented here have precipitated a change in the way protosteloid amoebae are perceived in two ways: (1) by expanding their known habitat range and (2) by forcing us to think of them as amoebae that occasionally form fruiting bodies rather than as primitive fungus-like organisms. Prior to this work protosteloid amoebae were thought of as terrestrial organisms. Collection of substrates from aquatic habitats …

The Effects Of Phosphorus Enrichment On Leaf Litter Stoichiometry In A Forested Stream, Bryant Baker

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

The effects of nutrient (N and P) enrichment on leaf litter decomposition in streams have been investigated extensively, but few have explored how P addition alone affects leaf litter stoichiometry (namely the C:P ratio). This study examined how the P content, C:P ratio and decomposition of two types of leaf litter (the recalcitrant Quercus stellata and the more labile Acer saccharum) responded to P enrichment from nutrient diffusing substrata (NDS) which was either unenriched agar or agar enriched with a moderate or high level of P. Leaf litter was sealed in 0.05 mm mesh bags, which excluded invertebrates, housed with …

Health Beliefs And Socio-Cultural Factors That Predict Cervical Cancer Screening Behaviors Among Hispanic Women In Seven Cities In The Upstate Of South Carolina, Arelis Moore De Peralta

All Dissertations

Cervical cancer is one of the most common reproductive cancers among women in the United States. The incidence and mortality rates of cervical cancer among Hispanic women in the U.S. are almost two times higher than non-Hispanic Whites. Cervical cancer screening is associated with early cervical cancer detection and, thus, with reductions in cancer morbidity and mortality. In Hispanic populations, where cancer rates are disproportionately high, it is important to conduct research that accounts for the influence of culture in health-seeking behaviors. The purpose of this study was to use the Health Belief Model (HBM) as a theoretical framework to …

Arsenic Represses Myogenesis And Neurogenesis Through Epigenetic Mechanisms, Repressed Transcription Factors, And Altered Wnt Signaling Pathway, Gia-Ming Hong

All Dissertations

Arsenic is a toxicant commonly found in water systems around the world. Evidence from epidemiological studies indicates that chronic arsenic exposure can result in cancer, central nervous system and sensory deficits, effects on development, and neuromuscular deficits. However, the molecular mechanism of arsenic's toxicity remains largely unclear. In this study, both C2C12 mouse myoblast cells and mouse embryonic stem cells (mESCs) were used as models of arsenic mediated developmental toxicity in humans to investigate the effects of sodium arsenite on cellular differentiation.
Results from our first and second studies indicate that exposure of 20nM sodium arsenite to C2C12 mouse myocyte …

However, it still faces challenges of being considered a reliable and consistent tool for producing normative data in the allied healthcare. Because there is little to no evidence for the Wii-fit balance board as a valid balance assessment tool for clinical and/or research usage, the significance of this study is …

A Comparison Of The Effectiveness Of Scent Lures On Attracting Mesopredators, Tom Batter

Department of Environmental Studies: Undergraduate Student Theses

A mesopredator is a medium-sized middle trophic level predator such as a raccoon (Procyon lotor), red fox (Vulpes vulpes), striped skunk (Mephitis mephitis), or coyote (Canis latrans; Crooks and Soule 1999). Mesopredators have long been trapped for recreational, economic, or academic reasons. Throughout human history trapping has been used to capture animals for food and skins, as well as to prevent personal harm and property damage from predators. In order to increase the probability of success, scent lures are often used as an attractant (Geary 1984, Mills et al. 2010, Schlexer 2008).

The Structure Of Energy Production And Redistribution Among Tsimane' Forager-Horticulturalists, Paul L. Hooper

Anthropology ETDs

This dissertation constitutes an integrated analysis of the Tsimane' economic subsistence system. Its analyses are guided by a body of evolutionary theory which posits that life history traits, the structure of social relationships, and nature of economic production co-evolve in patterned and predictable ways. This theory specifically suggests that, for humans, the returns to embodied capital development and declines in reproductive efficiency late in life interact to produce: prolonged development, extended lifespan, menopause, and a predominantly downward three-generational system of energetic provisioning. The current analyses of Tsimane' work effort, production, and transfers are consistent with this theory in the following …

Increasing Profitability Of Small Scale Cocoa Farmers Through Optimizing Replacement Rate, Mahrizal
